Part Change Notice #10853: CFA635 series Firmware revision 2.1.

Products Affected: CFA635-YYE-KS, CFA635-TMF-KS, CFA635-TFE-KS, CFA635-TMF-KL, CFA635-TFE-KL, CFA635-TFE-KU, CFA635-YYE-KL, XES635BK-TFE-KU, XES635BK-TMF-KU, XES635BK-YYE-KU, CFA635-TMF-KU, CFA635-YYE-KU
Date Issued: May 3, 2017
Summary: CFA635 series Firmware revision 2.1.
Last revision: 2.0
Description: The CFA635 series of advanced display modules will be changing from the previous firmware revision of 2.0 to the new firmware revision 2.1.
Reason: As part of our continuous improvement, the firmware has been updated for use with the hardware v1.5.
Impact: The new firmware is designed with a priority of backward compatibility. The following commands will differ from earlier versions:

Command 1 (0x01) – Get Hardware and Firmware Version
This command will report the following strings:
Serial Versions (KS) – CFA635: h1.5,f2.1
USB Versions (KU) – CFA635: h1.5 f2v1

Commands 18,19 and 20, which control the temperature sensors on the FBSCAB, have been limited to support the FBSCAB's maximum of 16 temperature sensors.
Recommendation: Design changes have been made to maximize backward compatibility. For most applications, the CFA635 hardware revision 1.5 will be a form and fit replacement.

If your application uses ATX power supply control, fan control, or temperature measurement through the SCAB, you will need change to the equivalent FBSCAB components.

We recommend testing the new version CFA635 in your system to verify compatibility.
Availability: CFA635 firmware version 2.1 will begin shipping installed in hardware version 1.5 in the second quarter of 2017 after the inventory of hardware version 1.2 is depleted.

Part Change Notice #10852: CFA635 series Hardware revision 1.5

Products Affected: CFA635-YYE-KS, CFA635-TMF-KS, CFA635-TFE-KS, CFA635-TMF-KL, CFA635-TFE-KL, CFA635-TFE-KU, CFA635-YYE-KL, XES635BK-TFE-KU, XES635BK-TMF-KU, XES635BK-YYE-KU, CFA635-TMF-KU, CFA635-YYE-KU
Date Issued: May 3, 2017
Summary: CFA635 series Hardware revision 1.5
Last revision: 1.2
Description: The CFA635 series of advanced display modules will be changing from the previous hardware revision 1.2 to the new hardware revision 1.5.
Reason: As part of our continuous improvement, the processor and PCB layout have been changed to improve availability, manufacturability, and quality
Impact: The revised CFA635 series has Wide Temperature (-20°C to +70°C) operating range. Part numbers have changed accordingly:
TMF series modules will become TML series.
TFE series modules will become TFK series.
YYE series modules will become YYK series.

The CFA635 series now supports a single FBSCAB. The SCAB is no longer supported:

All four fans may be used on serial (-KS) and logic level (-KL) modules.
Maximum temperature sensors is 16.

ATX power supply control functions previously supported by J8 on the SCAB are now supported by H1 on the CFA-635.

The power supply and backlight circuits have been improved:
The backlight driver is a constant current design—the backlight current and brightness are now insensitive to supply voltage variations.

The incoming power supply range is 2.5v to 5.5v, so the CFA635 can easily be used in 3.3v systems.

The yellow backlight of the CFA635-YYK series is redesigned to improve brightness.

ATX functions supported by J8 on the SCAB are now supported by H1.

Command 1 (0x01) – Get Hardware and Firmware Version
This command will report the following strings:
Serial Versions (KS) – CFA635 h1.5,f2.1
USB Versions (KU) – CFA635 h1.5,f2.1

The command set, fan electrical specifications, temperature electrical specifications and mechanical dimensions are unchanged.
Recommendation: Design changes have been made to maximize backward compatibility.

If your application uses ATX power supply control, fan control, or temperature measurement through the SCAB, you will need to change to the equivalent FBSCAB components.

We recommend testing the new version CFA635 in your system to verify compatibility.
Availability: CFA635 hardware version 1.5 will begin shipping in the second quarter of 2017, after the inventory of version 1.2 is depleted.

Part Change Notice #10405: Reactivation of the CFA635 family of modules with 1v2 hardware and supporting firmware.

Products Affected: CFA635-YYE-KS, CFA635-TMF-KS, CFA635-TFE-KS, CFA635-TMF-KL, CFA635-TFE-KL, CFA635-TFE-KU, CFA635-YYE-KL, XES635BK-TFE-KU, XES635BK-TMF-KU, XES635BK-YYE-KU, CFA635-TMF-KU, CFA635-YYE-KU
Date Issued: March 20, 2012
Summary: Reactivation of the CFA635 family of modules with 1v2 hardware and supporting firmware.
Last revision: 1v1
Description: The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The changes to the CFA635 1v2 hardware are as follows:

  1. LCD controller changing from Samsung S6A0073 to Rockworks RW1067

  2. Supporting driving circuitry between the LCD controller and the LCD glass has been updated to support the Rockworks RW1067

  3. The PCB layout has been updated to support the Rockworks RW1067

  4. Firmware updates to support the Rockworks RW1067 and functional improvements – See PCN #10406


The only changes to the CFA635 family are to support the Rockworks RW1067 controller. There are no other physical changes to the CFA635.
Reason: When the CFA635 family was scheduled for End of Life (see PCN #10365) there was no replacement available for the Samsung S6A0073 LCD controller. The CFA735 family was designed as replacement for the CFA635, allowing a path for improved performance, graphics, and the ability for end users to write their own firmware to take advantage of the capabilities of the enhanced hardware.

After the development of the CFA735 family, the RW1067 was developed as a replacement for the Samsung S6A0073 LCD controller for Crystalfontz America, Inc by Rockworks (China).
Impact: This announcement impacts all variants, interfaces, and part numbers that currently use the CFA635 family of modules. The CFA635 can continue to be used in current and future designs.
Recommendation: Continue to order and build with the CFA635 as required by production schedules. Transition to the CFA635 1v2 hardware and supporting firmware should be a seamless process. Engineering samples for qualification for the revised CFA635 are scheduled to be available Q3 of 2012.
Availability: Q2 2012
Review / Update customer Defined Part custom firmware

Q3 2012
New hardware and supporting firmware available for engineering samples

Estimated - Begin transition to 1v2 hardware as 1v1 hardware inventory is depleted

NOTE: We will not ship production orders of 1v2 hardware until the 1v1 inventory is depleted

Q4 2012
Estimated - CFA635 1v1 hardware to be exhausted, transition to CFA635 1v2 hardware complete
Price Change: No scheduled price change at this time.

Part Change Notice #10406: Supporting firmware for the reactivation of the CFA635 family of modules.

Date Issued: March 20, 2012
Summary: Supporting firmware for the reactivation of the CFA635 family of modules.
Last revision: 1v6
Description: The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The majority of the changes to the firmware have been in support of the RW1067 LCD controller and are transparent to the user interface. The changes to the CFA635 2v0 firmware:

For hardware changes related to this firmware update, please see PCN #10405

Updates
Command 1 (0x01): Get Hardware & Firmware Version
Modules with the serial interface, -KL and -KS suffix, will report: CFA635:h1v2,s2v0
Modules with the USB interface, -KU suffix, will report: CFA635:h1v2, u2v0

Command 12 (0x0C): Set LCD Cursor Style
Option 4 = inverting, blinking block is no longer supported. This option will result in a blinking underscore.

Command 22 (0x16): Send Command Directly to the LCD Controller
Any command sent specifically to the Samsung S6A0073 will need to be reviewed / modified for the commands / registers of the Rockworks RW1067. Please contact the Crystalfontz Engineering Support Team at support@crystalfontz.com for the RW1067 datasheet.

Enhancements
Command 28 (0x1C): Set ATX Power Switch Functionality
Added auto polarity switch.
